📰 What Happened
Australia's statistics agency will change the weights in its inflation basket in January. The basket is a list of goods and services that typical households buy. Each item gets a share based on how much people spend on it.
The Australian Bureau of Statistics last reweighted the basket in late 2025. This year, food, health and transport took up bigger shares. The change was pushed back from the end of 2026 to January.
The news comes after inflation rose to 4.3 per cent in the year to September, up from 4 per cent in August.
🔍 The Backstory
The consumer price index tracks prices across the economy. It is used to set pensions, wages and interest rates. If the basket is out of date, the inflation number can be wrong.
Households have changed how they spend since the pandemic. People spend more on housing, insurance and health, and less on some goods. Statisticians update the basket to keep up with that shift.
Retail expert Lisa Asher says the aim is to show what people are really buying now, not what they bought years ago.
🎯 Why It Matters
Inflation decides how much your money buys and whether rates go up. A better measure means better decisions for everyone.
